Add local and global hooks for check current activity

[stalkerg]

Very often add active class not enough. For example for Bootstrap navigation panel, you should add class to a parent element. Why listen to history not enough too? Your route can contain params and you can't easily compare current location path and route path.
Extend RouterLink not possible because your route path can accessible from many URLs.
I know current solution a little hacky but maybe right now it's better than nothing.

I hope this project still active and will be the best solution for Svelte.

For example, https://github.com/TehShrike/svelte-state-renderer exist very useful function:
"asr.stateIsActive" it solves most of the problems with navigations.
